A7670C GSM module AT command call setup

Official Hardware Retired GSM Shield
1

I've set up A7670C GSM module using AT command, but I'm stuck with 2 of them.

  1. When I call the number in the GSM, it automatically disconnects/ends the call, without me sending the ATH command. How can I make it in such a way that it keeps ringing till I send the ATH command?

  2. When I receive a text message, it's displayed as written from the phone in the serial monitor (ex: "Hello World"), but when I receive a call, the message is displayed in hexadecimal format in the serial monitor,

"0059006F00750020006D0069007300730065006400200061002000630061006C006C002000660072006F006D"

and when I convert it to ASCII, I can read it "You missed a call from ...". How can I receive the message directly in ASCII, same as the text message?

Thank you.

First, better you copy/paste your program.
(you can partially mask tel number.)
Without program, impossible to respond
May be it is in setup , may be in loop or in declaration :wink:
